Sendmail - STARTTLS not appear on one client
by happymaster23 01 Dec '08

01 Dec '08

Hi, I have Sendmail configured to use STARTTLS for authentication. On all internet connections and computers (that I have tested) works connection over encrypted SMTP flawlessly. Today I was setting up mail client on PC of my customer and standardily checked boxes, that I want to use SSL for POP3 and SMTP. Next I wanted to check configuration (by sending email from this mailbox to this mailbox) but it does not work. So I have opened telnet, connected via port 25 and writed "ehlo hostname" and then finded out, that there is missing STARTTLS. Is possible, that some bad configuration on client side (firewall, etc...) can cause this error including that this function is missing in printout of ehlo? POP3S working good. >From Sendmail log (/var/log/maillog): Nov 28 19:31:23 server sendmail[11163]: xxx: xxxxx.jizmorava.adsl-llu.static.bluetone.cz [85.207.xxx.211] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA Thank you very much

how can I stress a server?
by Rudi Ahlers 30 Nov '08

30 Nov '08

Hi all, I have a server, with an Intel DG35EC motherboard, Q9300 CPU, 8GB Kingston DDRII RAM which can't take a lot of load. I have 4 XEN VPS's on there, which doesn't consume more than 4GBM RAM at this stage. Yet, the machine sky rockets at some times. I've moved the XEN VPS's to another server, with 4GM RAM, and it doesn't cause the same problems. So, apart from memtest86 how else can I stress test the server to find out what the problem is? -- Kind Regards Rudi Ahlers

Installing CentOS security updates to RHEL machines? (RHN subscription expired)
by Alexander Farber 30 Nov '08

30 Nov '08

Hello, I hope my question is not annoying. I work as sysadmin at a 400 users firm and we have around 20 CentOS 4/5 servers and VMs and CentOS is awesome, thank you! However we have 4 important SAP-servers running RHEL5 and our RHN subscription has unforunately expired and buying it again is not an option right now. Installing CentOS is not an option too, because we'd have to pay for SAP-reinstall. Has anybody have been in a similar situation and figured out a good way to make "yum update" on RHEL machines to work against CentOS repositories? Regards Alex

Enterprise Package Tracker
by Vandaman 30 Nov '08

30 Nov '08

Is there a utility such as rpmfind that exists for enterprise rpms? One could locate rpms from various repos e.g. - Centos base, extras, plus - EPEL - RPMForge - KBS repos Due to the requirement of a subscription, upstream or others like Oracle Unbreakable linux couldn't be listed. Regards, Vandaman.

installation help
by Kevin Kempter 30 Nov '08

30 Nov '08

Hi All; I'm trying to instal CentOS on my new laptop but I've run into a few issues. It's a Dell Precision M6400 - I'm installing CentOS 5 (64bit) running KDE I have 3 issues: 1) I cannot get the wireless to work 2) I cannot get sound to work 3) I cannot get the full screen resolution I can go to administration --> display and under the 'Hardwae' tab I can configure the display as a generic or as a Dell 1920x1200 but no matter what I choose the 'Settings' tab only lets me choose a max of 1400x1050 I can get the wireless and sound to work in Fedora 10 but I'm not sure how to tell specifically what devices they are.. I thought I could use Fedora 10 to help debug the sound & wireless. Thanks in advance for any help ...

IMAP rule problem
by Anne Wilson 29 Nov '08

29 Nov '08

I have a problem with local mail on this netbook. I'm sure it's something obvious, but I could use another brain's input. Fri, 2008-11-28 13:15:27 - TCP Packet - Source:192.168.0.7,58711 Destination:88.97.17.41,143 - [IMAP rule match] Fri, 2008-11-28 13:15:27 - TCP Packet - Source:192.168.0.7,58711 Destination:192.168.0.40,143 - [IMAP rule not match] The first one delivers mail through my Roaming profile, using googlemail's smtp. The second one sends to my own smtp server for local delivery, something that's happening all the time from other boxes. Since my brain is reluctant to get in gear over this, where should I be looking for the problem? Anne

That address (192.168.0.7) is a dhcp address, which must have been my laptop wifi connection, and since I had no wired connection at the time, if there had been anything really wrong I wouldn't have been able to use my mail, and I would have known about it. It probably represents a fleeting problem. > Of course the non-public numbers don't go outside your network, so > there may be NATting going on (specifically in the non- public --> > public case) that's obscuring the issue. > Since it's the router, the commonality seems to rule that out. > By the way, you seem to have asked about this back in March. > Did I ask something similar? I don't recall - but then I don't recall what I had for breakfast yesterday. I'll look back and see if I can find anything. All the same, thanks to your breaking my circle of thinking, I don't think there's really a problem. If it occurs again I'll look more closely. BTW, your reply-to plays havoc with normal list behaviour. Anne

Does anyone here have a good working knowledge of the command line interface to Bugzilla? If so, please contact me off-list as this is OT here, but my inquiry on the bugzilla list met with silence.... Thanks. Mark Hull-Richter Linux/C Developer
